Head trauma in children, part 1: admission, diagnostics, and findings

Interobserver reliability and diagnostic accuracy of prehospital triage for identifying traumatic brain injury in paediatric patients: a systematic review

PURPOSE

The consistency and accuracy of paediatric TBI triage tools can be affected by different factors, such as patients' characteristics and the level of knowledge and skill of the caregiver. This systematic review included all the available data on the level of agreement between paramedics and ED physicians about the reliability of tools to identify paediatric TBI and the diagnostic accuracy of several such tools in prehospital settings when used by paramedics.

METHODS

MEDLINE (OVID), EMBASE (OVID), Cochrane Library (OVID), and CINAHL Plus (EBSCO) databases were searched from inception to 27 October 2022. Quality, bias, and applicability were assessed using COSMIN for interobserver reliability studies and QUADAS-2 tool for diagnostic accuracy studies. Narrative synthesis was employed because data were unsuitable for meta-analysis.

RESULTS

Initial searches identified 660 papers in total. Five met the inclusion criteria. Two studies showed moderate agreement between paramedics and ED physicians for GCS assessment. The PTS overtriage rate was 10% and the undertriage rate was 62%, while the triage tape had an overtriage rate of 18% and an undertriage rate of 68%. Pre-hospital GCS had 86.67% sensitivity and 71.43% specificity [95% CI]: 0.74-0.96 for neurosurgically significant TBI.

CONCLUSION

Low level of GCS agreement and poor diagnostic accuracy may cause further harm to the patient; thus, further studies are recommended to improve the prehospital management of children with head injuries.

Prognostic factors of acute neurological outcomes in infants with traumatic brain injury

PURPOSE

The purpose of this study is to clarify risk factors for poor neurological outcomes and distinctive characteristics in infants with traumatic brain injury.

METHODS

The study retrospectively reviewed data of 166 infants with traumatic intracranial hemorrhage from three tertiary institutions in Japan between 2002 and 2013. Univariate and multivariate analyses were used to identify clinical symptoms, vital signs, physical findings, and computed tomography findings associated with poor neurological outcomes at discharge from the intensive care unit.

RESULTS

In univariate analysis, bradypnea, tachycardia, hypotension, dyscoria, retinal hemorrhage, subdural hematoma, cerebral edema, and a Glasgow Coma Scale (GCS) score of ≤ 12 were significantly associated with poor neurological outcomes (P < 0.05). In multivariate analysis, a GCS score of ≤ 12 (OR = 130.7; 95% CI, 7.3-2323.2; P < 0.001), cerebral edema (OR = 109.1; 95% CI, 7.2-1664.1; P < 0.001), retinal hemorrhage (OR = 7.2; 95% CI, 1.2-42.1; P = 0.027), and Pediatric Index of Mortality 2 score (OR = 1.6; 95% CI, 1.1-2.3; P = 0.018) were independently associated with poor neurological outcomes. Incidence of bradypnea in infants with a GCS score of ≤ 12 (25/42) was significantly higher than that in infants with GCS score of > 12 (27/90) (P = 0.001).

CONCLUSIONS

Infants with a GCS score of ≤ 12 are likely to have respiratory disorders associated with traumatic brain injury. Physiological disorders may easily lead to secondary brain injury, resulting in poor neurological outcomes. Secondary brain injury should be prevented through early interventions based on vital signs and the GCS score.

Radiological Correlates of Raised Intracranial Pressure in Children: A Review

Radiological assessment of the head is a routine part of the management of traumatic brain injury. This assessment can help to determine the requirement for invasive intracranial pressure (ICP) monitoring. The radiological correlates of elevated ICP have been widely studied in adults but far fewer specific pediatric studies have been conducted. There is, however, growing evidence that there are important differences in the radiological presentations of elevated ICP between children and adults; a reflection of the anatomical and physiological differences, as well as a difference in the pathophysiology of brain injury in children. Here in, we review the radiological parameters that correspond with increased ICP in children that have been described in the literature. We then describe the future directions of this work and our recommendations in order to develop non-invasive and radiological markers of raised ICP in children.

Emergency Neurological Life Support: Traumatic Brain Injury

Traumatic Brain Injury (TBI) was chosen as an Emergency Neurological Life Support topic due to its frequency, the impact of early intervention on outcomes for patients with TBI, and the need for an organized approach to the care of such patients within the emergency setting. This protocol was designed to enumerate the practice steps that should be considered within the first critical hour of neurological injury.

Head Injury in Children: Has a Change in Circumstances Caused an Increase in Treatment Numbers?

The number of hospitalizations for head injuries in children is rising. The exact causes remain unclear. We analyzed data of children aged between 0 and 18 years who sustained a head injury between 2010 and 2011. The analysis focused on data related to demographics, trauma mechanism, clinical course, results of imaging scans, concomitant injuries, and outcome. A total of 794 inpatient cases of head injury were treated. The leading mechanism of injury was a fall (at home) primarily at the age of 1 to 4 years (46.5%), with the majority of the children sustaining a mild brain injury (764, 96.2%). Neurosurgery was performed in 21 (2.64%) cases; average hospital stay was 2.9 days (range: 0-68 days). This study is not able to confirm that children are increasingly being brought to the hospital by their parents because of new trauma mechanisms or parents' uncertainty, nor can we confirm that the number of nonaccidental injuries is rising.

Prognostic value of shock index in children with septic shock

OBJECTIVES

Septic shock is frequent in children and is associated with high mortality and morbidity rates. Early recognition of severe sepsis improve outcome. Shock index (SI), ratio of heart rate (HR) and systolic blood pressure (SBP), may be a good noninvasive measure of hemodynamic instability that has been poorly studied in children. The aim of the study was to explore the usefulness of SI as an early index of prognosis for septic shock in children.

METHODS

The study was retrospective and performed in 1 pediatric intensive care unit at a university hospital. The following specific data were collected at 0, 1, 2, 4, and 6 hours after admission: HR and SBP for SI calculation and lactate concentration. Patients were divided into 2 groups according to their outcome (death/survival).

RESULTS

A total of 146 children admitted with septic shock between January 2000 and April 2010 were included. Shock index was significantly different between survivors and nonsurvivors at 0, 4, and 6 hours after admission (P = 0.02, P = 0.03, and P = 0.008, respectively). Age-adjusted SIs were different between survivors and nonsurvivors at 0 and 6 hours, with a relative risk of death at these time points of 1.85 (1.04-3.26) (P = 0.03) and 2.17 (1.18-3.96) (P = 0.01), respectively. Moreover, an abnormal SI both at admission and at 6 hours was predictive of death with relative risk of 1.36 (1.05-1.76).

CONCLUSIONS

In our population of children with septic shock, SI was a clinically relevant and easily calculated predictor of mortality. It could be a better measure of hemodynamic status than HR and SBP alone, allowing for the early recognition of severe sepsis.

Does a prehospital Glasgow Coma Scale score predict pediatric outcomes?

BACKGROUND

Although the Glasgow Coma Scale (GCS) score is widely used by medical professionals to evaluate and predict neurological outcomes, studies using the prehospital (P) GCS score to predict neurological outcomes in children are few.

OBJECTIVE

The objective of this study was to determine the agreement between the P GCS score and the emergency department (ED) GCS score, and the association between P GCS score and outcomes at hospital discharge in pediatric patients 5 to 18 years of age.

METHODS

Medical record review of children 5 to 18 years old with traumatic brain injury (TBI) was conducted. Children with documented P and ED GCS scores were eligible for enrollment. The hospital records of each enrolled child were reviewed, and the Glasgow outcome score and the disability rating scale scores were calculated. Agreement between the P and ED GCS scores was calculated using χ (κ statistic).

RESULTS

One hundred eighty-five subjects were included. There was strong agreement between P and ED GCS scores (κ = +0.69; confidence interval, 0.57-0.81). The Glasgow outcome score category improved with improving GCS category. The median disability rating scale score was also similar for P and ED GCS scores and was higher with decreasing GCS.

CONCLUSIONS

Our data showed strong agreement between P and ED GCS scores. Also, there was strong association between P GCS scores and short-term outcomes in children with TBI. The results support the use of GCS in prehospital transport destination guidelines for children with TBI.

Risk factors for mortality in children with abusive head trauma

OBJECTIVE

We sought to identify risk factors for mortality in a large clinical cohort of children with abusive head trauma.

STUDY DESIGN

Bivariate analysis and multivariable logistic regression models identified demographic, physical examination, and radiologic findings associated with in-hospital mortality of children with abusive head trauma at 4 pediatric centers. An initial Glasgow Coma Scale (GCS) ≤ 8 defined severe abusive head trauma. Data are shown as OR (95% CI).

RESULTS

Analysis included 386 children with abusive head trauma. Multivariable analysis showed children with initial GCS either 3 or 4-5 had increased mortality vs children with GCS 12-15 (OR = 57.8; 95% CI, 12.1-277.6 and OR = 15.6; 95% CI, 2.6-95.1, respectively, P < .001). Additionally, retinal hemorrhage (RH), intraparenchymal hemorrhage, and cerebral edema were independently associated with mortality. In the subgroup with severe abusive head trauma and RH (n = 117), cerebral edema and initial GCS of 3 or 4-5 were independently associated with mortality. Chronic subdural hematoma was independently associated with survival.

CONCLUSIONS

Low initial GCS score, RH, intraparenchymal hemorrhage, and cerebral edema are independently associated with mortality in abusive head trauma. Knowledge of these risk factors may enable researchers and clinicians to improve the care of these vulnerable children.

Head trauma in children, part 3: clinical and psychosocial outcome after head trauma in children

With the aim of determining long-term outcome, the authors approached 38 families (average 2.1 years after trauma) with a questionnaire, following the acute-clinical treatment of head trauma of their children. Long-term damage was restricted almost exclusively to patients presenting with a Glasgow Coma Score < or =8. Paresis (16%), cranial nerve damage (13%), incontinence (5%), or coordinative disturbances (18%) continued. The older children stated that they influenced their life to a great extent (11%). Furthermore, many had mental and cognitive problems that occur quite frequently even in children with light head trauma and often only manifest after release from hospital. This causes problems and results in inferior performance (26%), especially at school, which is further complicated through lengthy periods of absence. The parents, especially, mentioned behavioral problems such as social withdrawal or aggressive demeanor, which led to tension also inside the family. A persistent vegetative state is rare after head trauma in children.
